1.1269 (DIN EN 10132 : 2021-11)	1.1269	DIN EN 10132 : 2021-11	DIN EN 10132 : 2021-11 replaced by DIN EN 10132 : 2022-04	Replaced	Germany	C85S	C85S	The steel C85S is used as cold rolled strip for springs and special applications in thicknesses of up to 6 mm and as tempered cold strip in thicknesses from 0.30 to 3.00 mm. The cold-rolled steel strip for springs possess a very high precision of measurements and very good state of the surface.
